Question

Is there in the JDK or Jakarta Commons (or anywhere else) a method that can parse the output of Arrays.toString, at least for integer arrays?

int[] i = fromString(Arrays.toString(new int[] { 1, 2, 3} ); 

Answer 1

Pretty easy to just do it yourself:

public class Test {   public static void main(String args[]){     int[] i = fromString(Arrays.toString(new int[] { 1, 2, 3} ));   }    private static int[] fromString(String string) {     String[] strings = string.replace('[', '').replace(']', '').split(', ');     int result[] = new int[strings.length];     for (int i = 0; i < result.length; i++) {       result[i] = Integer.parseInt(strings[i]);     }     return result;   } }
